The invention provides a mixed gas generator, which belongs to the field of automobile safety protection, and comprises a tank body, a first chamber for accommodating compressed gas is arranged in the tank body, a first exhaust port is arranged on one end side, and a first rupture disk is arranged at the exhaust port; the starting assembly is at least partially arranged or contained in the tank body, heat and/or gas are/is generated after the starting assembly is started, the pressure in the tank body is instantly increased, the first rupture disk is opened, and the compressed gas in the tank body is exhausted through the first exhaust port; the slow-burning gas production medicine is arranged in the tank body, and after the starting assembly is started, the slow-burning gas production medicine is further ignited within 10-15 ms, and heat and/or gas are continuously conveyed to be supplied to the tank body and the air bag component communicating with the first exhaust port; wherein the combustion speed of the slow-combustion gas production medicine is smaller than or equal to 15 mm/s under the normal pressure, and the slow-combustion gas production medicine is slowly combusted within 10-6000 ms. By means of the treatment scheme, the airbag pressure drop caused by gas leakage and temperature drop is supplemented for the airbag, and it is guaranteed that enough internal pressure exists in the airbag to protect passengers from being hurt.

    本发明提供了一种混合式气体发生器,属于汽车安全防护领域,包括罐体,具有容纳压缩气体的第一腔室,一端侧设置有第一排气口,排气口处设置有第一爆破片;启动组件,至少部分地被安置在或包含在罐体内,启动后产生热量和/或气体,瞬间升高罐体内压力打开第一爆破片,使罐体内的压缩气体经第一排气口排出;缓燃产气药,设置在罐体内,启动组件启动后10‑15ms内进一步引燃缓燃产气药,持续输送热量和/或气体供给罐体和与第一排气口连通的气囊部件;其中,缓燃产气药在常压下,燃烧速度≤15mm/s,且在10‑6000ms内缓慢燃烧。通过本申请的处理方案,为气囊补充因为气体泄漏和温度下降导致的气袋压力下降,保障气囊内有足够的内部压力来保护乘员不受伤害。
